Our team’s project is Dr. Coli, an E. coli bacterium that produces a drug when and where it is needed in the human body. It does this in an intelligent way, such that the drug production meets the individual patient’s needs. And when the patient is cured, Dr. Coli eliminates itself from the body. To achieve this goal we divided our project into several subsystems. A detailed description about every subsystem can be found by clicking on one of the following pictograms.

The most important assets of our project are the different control mechanisms. Since these are very much dependent on kinetic and other constants, Dr. Coli heavily relies on proper modeling. Our Dry-Lab team has spent its summer setting up a computational model of Dr. Coli to completely simulate his actions. We constructed models of all the subsystems (components) in both CellDesigner and Matlab. All these subsystems have been characterised by their ODE's and have been simulated thoroughly. Together they form our full model of Dr. Coli. These models are only capable of simulating the behaviour of one Dr. Coli cell, so we implemented our own Software Tool that can work with multi cellular models.

After building the model frame, it was time to add the physical relevance to it. Kinetic constants were searched for and investigated by means of previous iGEM teams (e.g. ETHZ 2007), the parts characterizations on the Registry of Standard Biological Parts and popular biological literature databases such as Hubmed, ... Our own contribution would revolve around data analysis of the produced parts.

Working with concepts as modularity and abstraction, we worked out every subsystem (Output, Memory, Filter, ...) to eventually merge them all in our full model. By trial and error the system was adapted to achieve desired output quantities (amount of molecules, proteins, ...) given a representative input.

To take it a step further, a multi-cell model was build, to analyse crucial steps in cell division (e.g. Memory inheritance). A diffusion model was made to investigate HSL diffusion towards neighbouring cells and see what effects this generated on their Invertimer system.
